To all whom it may concern:

Be it known that we, FRANK B. KEALL, ALFRED HARRINGTON, and RICHARD W. C. BAssET'r, subjects of the King of England,

residing at Leicester, Leicestershire, Eng- .edge of the sole is pressed against the setting iron, the upper surface of the welt or sole is pressed against the under surface of the indenting wheel.

It has been proposed to mount the indenting wheel on a slide which allows the wheel to move relatively to the edge settlng lron, against the action of a spring, so as to adapt the wheel for indenting Welts or corre sponding parts of different widths, the form of indenting wheel usually employed being frusto-conical, and the work being applied to it so. that the upper is pressed against the base of the cone. A

It is found, however, when using a device of this nature that since the pressure applied to the wheel by the welt or equivalent part is almost perpendicular in direction to the line alon which. the slide must move, considerable .frlction results. The resulting stiffness of motion in the slide causes damage to the upper through the undue pressure required between it and the base of the wheel, and also prevents the re turn motion of the wheel after it has been forced back from any cause during the edge setting operation so that the upper surface 'of the welt or corresponding part of the shoe is not indented over its full width.

A further. disadvantage of the combined edge setting and indenting devices at present in use is that they have only one edge setting surface above which the indenting wheel is centrally mounted. It is necessary in such devices to cut away the upper central portion of the edge setting surface, directly under the indenting wheel, in order to position the wheel low enough to press propcrlyon the upper surface of the welt or corresponding part of the shoe. The central portion of the edge setting face is its most important part in the setting operation, since the edge setting face is generally convex about an axis substantially perpendicular to the tread face of the sole which is being operated upon and accordingly the maximum pressure occurs just where the iron is cut away. The upper corner of the a sole edge is therefore insufficiently set, since regardless of the pressure applied to it;

Although this feature of the invention is shown 111 connection with a combined edge setting and indenting device, it should be understood that it may be useful in other combinations, or may be used upon a ma chine for performing the indenting operation only.

Another feature of the invention comprises a combined edge setting iron and indenting device, 1n which the lndentlng wheel and the edge setting face of the iron are properly positioned to crowd the upper corner of the sole edge between them without interfering with the normal operation of either one.

Other features of the invention will appear as the description proceeds.

In the accompanying .drawings which illustrate one form of the invention:

Fig: Sisa' section on the line 8 -8 of Fig: 6, showing thesole I The body 1 is adapted to be mounted on a machine which will rapidly oscillate it transversely. screw 2, a head 2 in which there is a Vertical slot having a filler block 4 mounted in the upper part of its front; end; by. means of the pin 5 and screw 6. Slidably mounted in the slot 3 isthe indenting wheel carrier. 7, which fits closely laterally in-the slot 3, but has some freedom of motion in. other directions. ltahas two. arms 8, 9 substantially at right angles, the. arm. 8 lyin between the bottom of the slot 3 andthe ller block 4,. and the arm 9 lying. between the filler block and the. rear vertical wall of the slot. The arm- 9has a: recess 10 andthebottom face of the slot 3l1211S a substantially registering recess 11. A thrust pin or hinge men'iber 12,. having rounded ends, ismounted in small sockets in the inner. ends of the recesses 10, 11. The pin 12 issmaller in cross-section than the recesses 10, 11 and therefore freedom for rocking. motion of the arm 9 exists. The arnrS and the fillerv block t have similar recesses 13, 14 respectively, in which athrust pin or hinge member 15 is mounted. The arm 9. has a recess 16 in which there is a spring. 17, the outer end of whichbears against the vertical rear wall. of the slot 3. The springlT tends to holdflthe arm Q'away from the rear wall of theslot 3, and in contact with the filler block 4, but when force is, exerted. against the base of the indenting wheel which is pivotally mounted at 19 upon the arm 8, the carrier 7 will swing. back against the spring17 on the pins 12, 15, which rock in the bearings at their ends Thus rockinginotion is substitiited for sliding, and it is.- found in practie'e that no stiffness in the movement of the carrier results from great upward pressure on the wheel 18, so that slight pressure of the upper against the base of the wheel 18 will move the carrier back, and

conversely, the spring 17 will at all. times hold. the base of the wheel 18. in, contact with the upper so that the whole of the. upper welt or corresponding surface will He properly indented;

The edge. setting iron 20 is mountedon the body 1 below the arm 8, by means of the screw 20="; It may be integralwith the head 2, or not, as desired. The ordinary type of iron is shown in Figs. 5 and- 6. It has one operating. surface. 21 which is generally convex about" an axis substantially perpendicular to the, tread face of the. sole 21" and shaped about a horizontal axis so as to conform to thedesired shape of: sole edge. It is often desired, to. form. ridges "22,

It has fastened to it by the" 23 at the top and bottom ofthe sole edge, respectively. Correspondin indentations are therefore formed on the aceof' the setting iron. In the ordi-narytypeof iron the overhang 2d of the-upper indentation 24 1s cut away at its-'-cen-tra=l portio1r27 in order to place the indentingwheel low enough to indent the welt properly. The removal of the ridge forming surface at its center, which is the point of maximum pressure, causes-the upper ridge to be formed by the portions of the iron as each side of the point of maximum pressure, and the best. ridge formingeflect isnot obtained, see-28; Fig. 6.
